A touchpad module includes an elastic bracket, a touch member, a plurality of connecting elements and a pressure sensing unit. The elastic bracket includes a plurality of cantilevers. The plurality of cantilevers have respective free ends and respective fixed ends. The plurality of connecting elements are connected with the respective free ends and the touch member. When the touch member is pressed in response to an external force, the external force is transmitted to at least one free end through at least one connecting element, the at least one free end is rotated relative to the at least one fixed end in a direction away from the touch member, and the pressure sensing unit is subjected to deformation. According to the deformation, the pressure sensing unit senses a magnitude of a pressing force exerted on the touch member and generates a corresponding pressure sensing signal.

An input device includes a plate body, a first sensing element, a second sensing element and a control unit. The first sensing element and the second sensing element are respectively located at two ends of a diagonal of the plate body for sensing a first image and a second image corresponding to a touching object. The control unit is electrically connected with the first sensing element and the second sensing element. The control unit acquires a position characteristic value according to the first image and acquires an auxiliary position characteristic value according to the second image. Moreover, the control units recognizes a position of the touching object according to the position characteristic value and the auxiliary position characteristic value, and generates an output signal according to the position of the touching object.

A keyboard device includes plural keys, an image pickup device, and a processor. The processor is connected with the image pickup device. The image pickup device is used for capturing an operation image of the plural keys that are operated. Moreover, after an information image over the keyboard device is scanned by the image pickup device, a scanned image is obtained. According to the received operation image, the processor generates a corresponding operation signal to a touch device. Moreover, according to the scanned image, the processor generates a corresponding information signal to the touch device.

A car door opening pre-detection system for a car includes a first detecting module, a second detecting module and a control module. The first detecting module is installed within the car. The first detecting module issues a motion detecting signal according to a result of detecting a motion of a palm. The second detecting module is installed outside the car. When the car is stopped, the second detecting module is enabled to selectively provide a first detection range or a second detection range. The control unit judges whether a car door of the car is about to be opened according to the motion detecting signal. When the car is stopped and the control module judges that the car door is about to be opened, the second detecting module provides the second detection range to detect whether there is a moving object behind the car.

A touch pen includes a main body, a connector, a first conductive pen tip, a second conductive pen tip and a switching module. The connector is disposed within the main body, and located at a first end of the main body. The first conductive pen tip and the second conductive pen tip are detachably coupled with the connector. According to a result of judging whether the connector is coupled with the first conductive pen tip or the second conductive pen tip, the switching module controls the operation mode of the touch pen. When the first conductive pen tip is coupled with the connector, the touch pen is in an active operation mode under control of the switching module. When the second conductive pen tip is coupled with the connector, the touch pen is in a passive operation mode under control of the switching module.

An input device includes an input interface, a power module, a wireless charging module, a solar charging module and a controller. The power module provides electricity to the input device. The wireless charging module is used for wirelessly charging an electronic device. The solar charging module is used for charging the power module or providing electricity to the wireless charging module. When the controller detects that an electricity quantity percentage of the power module is lower than a predetermined value, the controller controls the solar charging module to charge the power module. When the electronic device is in communication with the input device, the controller controls the solar charging module to the provide electricity to the wireless charging module, and the electronic device is wirelessly charged by the wireless charging module if the electronic device is within a charging range.

Input device

A multi-mode touch input device includes a first touch input device and a second touch input device. When a first lateral surface of the first touch input device and a first lateral surface of the second touch input device are combined together, both of the first touch input device and the second touch input device are operated in a keyboard mode, and the first touch input device and the second touch input device are collaboratively defined as a touch keyboard. When a second lateral surface of the first touch input device and a second lateral surface of the second touch input device are combined together, both of the first touch input device and the second touch input device are operated in a handwriting tablet mode, and the first touch input device and the second touch input device are collaboratively defined as a handwriting tablet.

Multi-mode touch input device

An input system includes an electronic device and a touchpad device. When the application program installed in the electronic device is activated, a target object is displayed on a display screen of the electronic device. A projection device of the touchpad device generates an object projection image of the target object. When the user moves the object projection image with the hand, the touchpad device detects a moving trajectory of the hand and generates the moved object projection image. Consequently, the target object shown on the electronic device is synchronously moved with the object projection image.
